Check Engine Light Flashing
When the check engine light is flashing on a 2019 Lexus ES 300h, it indicates a severe condition that needs immediate attention—often a misfire that can damage the catalytic converter, reduce hybrid system efficiency, or stress drivetrain components. At Park Place Lexus in Plano, TX, our technicians use Lexus-approved diagnostics and hybrid-system training to quickly isolate whether the issue stems from ignition components, fuel delivery, catalytic converter concerns, or hybrid-specific sensors. Immediate dealer attention helps avoid costly downstream repairs and can often remediate the problem before it affects long-term reliability. We emphasize transparent estimates, OEM replacement parts, and a documented repair history that protects your vehicle’s value.
We recommend against driving with a flashing light. Stop safely and have the vehicle towed to Park Place Lexus if necessary.

Ask about our available service specials and note that we offer service financing so you can get the repair done now and pay over time.

2019 Lexus ES 300h Check Engine Light Reset
Resetting the check engine light on a 2019 Lexus ES 300h can be simple or complex depending on the underlying cause. While some owners can clear codes temporarily via battery disconnect or code readers, Park Place Lexus recommends a professional diagnosis to ensure the root cause is repaired rather than masking symptoms. Resetting without repair may lead to recurring failures, voided warranties, or unpredictable hybrid performance. Our technicians use Lexus diagnostic software to read pending and stored codes, verify repairs, and confirm the system is functioning properly before clearing codes—protecting you from repeat visits and unnecessary expense.
Using the dealership ensures transparency, OEM parts, and documented repairs that preserve warranty coverage and vehicle health. We frequently find that correct diagnosis and repair at Park Place Lexus save customers money over time compared with piecemeal fixes. We provide written estimates, explain immediate and long-term savings, and offer service financing to make timely repairs accessible. Before we clear any codes, we confirm repairs are complete and the issue resolved—then we clear codes and road-test the vehicle for peace of mind. To get a full diagnostic and professional reset, schedule appointment online and review our service specials.
2019 Lexus ES 300h Check Engine Light Codes
